TYPOGRAPHICAL MACHINE.

Specification of Letters Patent.

Patented June 9, 1914.

Application filed Decemberl?, 1912. Serial No. 737,168.

To all whom it may concern Be it known that I, DAVID S. KENNEDY, acitizen of the lUnited States, and a resident of the borough ofBrooklyn, county of Kings, and State of New York, have invented a newand useful Improvement in Typographical Machines, of which the followingis a specification.

My invention relates to machines in which printing slugs or bars arecast in a slotted mold and then delivered therefrom by an ejector bladewhich advances against' the edge of the slug. In many of these machinesthe molds are Variable or adjustable in length in order to produce slugsfor printing` columns or pages of different widths; and in connectionwith such an adjustable mold is frequently employed a composite ejectorhaving its parts so constructed and combined that its operative portionmay be varied in` width to correspond with changes in the length of themold slot. As illustrated for instance in Letters Patent of the UnitedStates, No. 967,976 to John R. Rogers, the `ejector blade iscomposed ofa series of parallel sections arranged edge to edge, and a mechanism isrovided whereby any desired number of tliese sections can be connectedwith the actuating slide, while the others are left free therefrom. Inthe operation of such machines, it sometimes occurs, at the" hands of aninexperienced or careless operator, that an attempt is made to connectordisconneot the sections at an improper time, and generally when themachine is in operation. This attempt sometimes results in injury to theparts, or in inconvenience and loss of time, .which disadvantages it isthe object of my invention to prevent. To this end'I construct the partsso that the ejector sections maybe connected with and disconnected fromthe actuatin i devices ionly when the parts are in a pre eterminedposition, preferably when the machine is at rest and when the ejector iswithdrawn from the mold.

In the accompanying drawings, I have illustrated my invention inpreferred form and by way of example, and as applied to the style ofmachine already mentioned, but obviously many changes and variationstherein, and in its mode of application, will .tions remain free, Iemploy the l having its lower end arranged to Referring to the drawings:Figure l is a` perspective side view of the mold and ejecting devices,partly in section and partly broken away, having my invention appliedthereto; Fig. 2 is a sectional View on an enlarged scale, takensubstantially on the line 2-2 in Fig. 1;-Fig. 3 is a View of some of theparts, similar to Fig. l; F ig. 4 is a section taken substantially onthe line Lalf-el in Fig. Q; and Fig. 5 is a detached View of an ejectorsection and its actuating member.

As in the said Rogers patent, the mold disk A is provided with theusual` slotted mold B and is mounted upon the slide C, and the slide Dis arranged to reciprocate horizontally on the slide C for the purposeof actuating the ejector. The ejector proper E comprises a series ofparallel blades or sections e, which sections are arranged one aboveanother, and are guided between the vertical face of the mold slide C onone side and the vertical plate F on the opposite side. The severalsections are free to move forward and backward independently, and alsoso that any desired number may be brought into action jointly, to forman ejector of a vertical width corresponding to thellelngth of the slu`"which is being cast in the machine, wh 1 e the other sections remaininactive in their inner or backward position. Each ejector section e isactuated by a corresponding member G, which members are mounted ingrooves c1 formed in the mold slide C. In order that any requiredvnumber of the sections c may be coupled to the actuating slide D, whilethe other secvertically movable bar H, carried by the slide D, and

travel forward and backward on the rod I attached to the vertical slideJ. The parts and operation so far described are or may be substantiallythe same as those disclosed in the said Rogers patent, wherein also thesame letters of reference are employed.

The 'vertical slide J may be shifted by the pivoted hand lever K, whichis provided with a spring pressed locking handle K1 adapted to engageteethon the stationary sector K2, whereby the parts are held in positionto cause the selection of any desired number of ejector sections e.- Anindicator L connected to the lever K assiststhe operator in adjustingthe parts. The bar H is thus adapted to rise and fall behind the membersGr, and may be moved upward or downward to such position that it willdrive forward any desired number of sectionsl provided additional means,whereby the'- change maybe made only when the machine is at rest andwhen the ejector lE has been withdrawn from its normal position withinthe mold D. To this end I provide the sliding bar H with an inwardlyprojecting stud P, which in the said position-of the parts is free tomove u ward and downward in the vertical groove formed in the mold slideC, as shown in Fig. 3. Whenthe ejector slide D advances, the bar H movesforward and its stud P enters and engagesV one of the grooves c1, asshown in Figs. 1, 2 and 4, thereby locking the bar H against verticalmovement and thus preventing a change in the width of the ejector E.

` As before stated, in the ordinary position 0f rest, the ejector E, orthe effective portion thereof, is located partly within the mold B. Ifnow it be desired to alter the adjustment of the ejector, this can beeffected only by moving it rearwardly, or until the stud P is restoredto the groove R, when the bar H may be again shifted vertically to therequired extent. .The preferred means employed for this purpose are the"handle S connected t0 the arm S1, which is mounted on the same shaftwith the ejector lever S2, which in turn is connected to the ejectorslide D by the link S3. In this position of the parts (Fig. 3), themanipulation of the lever K effects the vertical movement of the bar H,so as to select a greater or less number of lsections e in order to varythe width of the ejector E.

Having thus described my invention, its construction and mode ofoperation, what I claim and desire to secure by Letters Patent of theUnited States is, as follows: i f

1. In a typographical machine, the combination of a movable ejectorvariable in width, a single adjusting device for controlling the widthof said ejector when the parts are in predetermined position, and vmeansfor preventing the operation of said device at any other time. y

2. In a typographical machine, the combination of a movable ejectorcomprising a plurality of sections, a single adjusting device forselecting the desired number of sections when the parts are inpredetermined position, and means for preventing the opcrationof saiddevice at any other time.

3; In a typographical machine, the combination of a movable ejectorcomprising a plurality of sections, actuating means therefor, a singleadjusting device for connecting the desired number of sections with theactuating means when the parts are in predetermined position, and meansfor preventing the operation of said device at any. other time. l

4. Ina typographical machine, the combination of a movable ejectorcomprising a plurality of sections, actuating means therefor, a singleadjustingdevice carried by said actuating means for controlling theconnection of the sectionstherewith when the parts are in predeterminedposition, and means for preventing `the operation of said device at anyother time.

5. In a typographical machine, thekcorn- 1 bination of a movablelejectorcomprising a plurality,y of sections, a lateral support formed withlongitudinal grooves and also with a transverse groove, and a connectindevicev movable both longitudinally an transversely of said support andprovided with la projecting stud .toI engage in vsaid grooves; wherebythetransverse movement of said device is prevented veXcep't when `itsstud stands in the transverse groove.

6. In a typographical machine, the combination of an ejector comprisinga lural.

ity of sections, a corresponding plura ity of actuating slides, asupport formed with longitudinal grooves in which said slides move, andformed also with a transverse groove, and a connecting andactuatingdevice movable both longitudinally and transversely of the support andlprovided with a projecting stud to engage in said grooves; whereby thetransverse movement of said device is prevented except when itsprojecting stud standsin the transverse groove.
